APPARATUS TO PREVENT FROTHING WHEN FILLING BEER INTO SIPHONS, &c.

SPECIFICATION forming part of Letters Patent No. 322,719, dated July 21, 1885.

Application filed January 8, 1885. (No model.)

To @ZZ whom, it may concern:

Be it known that I, FREDERIK HEYMAN, owner ofthe brewery Svanholm, 7 a subject of the King of Denmark, residing at Copenhagen, in the Kingdom of Denmark, have invented certain new and useful Improvements in the Apparatus for Filling Fermented Liquors in Siphons; and I do declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and igures of reference marked thereon, which forni a part of this specification, and in Which- Figure l is a partly sectional-view of my improved apparatus for filling fermented liquors in siphons. Fig. 2 is a partly sectional view of a slight modification of the same. Fig. 3 is a vertical sectional view of the tank or receiver for the liquor, the charging-pipe, the barrel or similar original package for the'liqnor, and the connectingpipe; and Figs. 4 and 5 are respectively a vertical and a vhorizontal sectional view of the cock which is inserted into the siphons.

Similar letters of reference indicate corresponding parts in all the figures.

y invention has relation to apparatus for filling fermented liquors in siphons, and it consists in the improved apparatus for filling such liquors in siphons, as hereinafter more fully described and claimed.

In filling fermented liquors into siphons a drawback has been experienced-viz., that the liquor absorbs the carbonio-acid gas necessary for producing a sufficient pressure to force the liquor out of the siphon, and consequently has been discharged in the shape of foam, which is very slow to settle, and the only way to avoid the creation of this foam has been to fill a comparatively small quantity of liquor in the siphon, so as to leave 4space for the gas; and this has rendered it rather unprotable and impractical to fill such liquors in siphons, the bulk of the containing-vessels being so much in excess of the liquor contained within them as to make them too bulky for common trade, and to avoid this drawback I have invented and practically tested the following method and accompanying apparatus, which, in brief, consists in first producing nearly a Vacuum in the siphon, thereupon filling the same with liquor containing only suiicient carbonio-acid gas to cause the liquor to foam in the desired manner to make it palatable, and thereupon introducing an air, which IWill term neutral air, under sufficient pressure to force the liquor out of the siphon. This air must be of such a character that it is not absorbed in the liquor, or at any rate onlyabsorbed in small quantities, so that it will not create foam; and, although Iprefer to use pure nitrogen, atmospheric air may be used after it has been passed either through red-hot pipes or through raw-cotton packing or similar ma` terial for the purpose of destroying the yeast germs or germs of fermentation contained in all atmospheric air, and which would produce a second fermentation, or the so-called acid fermentation, in the liquor, spoiling the same.

In the drawings, the letter A indicates the reservoir containing the liquor to be filled in the siphon. B indicates a tank in which a vacuum is kept up by means of an air-pump, C. D is the tank for containing the liquor charged with the desired quantity of carbonicacid gas, and E is the tank for containing th neutral air.

The tank D is connected with the reservoir AV by means of a pipe, F, which enters the bottom of the tank, and the reservoir is preferably placed above the tank, as shown in Fig. 3, so as to force the liquor into the tank by gravity.

The carbonio-acid gas is pumped into the tank through a pipe, G, entering the tank at the bottom and having a number of perforations for the escape of the gas through the liquor into the tank, a pump, H, serving to force the gas into the tank, and a pipe, I, extends from a safety-valve, J, at the top of the tank to the pipe K, which carries the gas to the pump, so that all gas which is forced into the tank at a pressure higher than that desired for the tank will escape through the said safetyvalve and passVV back into the pipe which 'can jries the gas from its reservoir to the pump.

valve opens into a pipe, O, passing back to pipe L at the other side of the pump.

The three tanks B, D, and E have pipes P opening into a three-way cock, Q, the plug B of which has a rectangularly-bent channel or bore, S, the lower arm of which bore opens through the lower end of the plug, while the bent arm of the bore registers with three apertures or ports, T, into which the vpipes l? open, the three ports being at right angles to each other, so that two parts are closed when one is open, or all three ports may be closed by turning the bent arm of the bore toward the closed side of the casing of the cock.

As near to a vacuum as is desired to be attained in the siphons before filling is kept up in the vacuum-tank'B by means of the airpump, and the liquor is kept in its proper tank under the pressure of carbonio-acid gas which it is desired to have, and the neutral air is likewise kept at its desired pressure, which is greater than the pressure ofthe carbonio-acid gas; and it will now be seen that by placing the siphon under the cock Q and turning the plug of the same so that the bore will register with the vacuum-pipe, the air will be rareedin the siphon to the same rarity which is kept up in the vacuum-tank, whereupon the plug of the cock is turned `so as to make'the Y sorbed in the liquor and thus create foam in drawing the liquor'from the siphon. In filling siphons by this method, however, the llquor as it passes from the liquor-tank into the siphon is apt to be formed into foam, passing from the tank under pressure into the vacuum in the siphon, and this foaming of the liquor necessitates the standing of the siphons for some time before they can be sufficiently filled, which of course retards the processor' filling; and for the purpose of avoiding this stoppage in filling the siphons I use a somewhat more complicated apparatus and slightly modified method, which I will proceed to describe.

The apparatus consists of the same three tanks B, D, and E, as the former apparatus, and of an additional tank, U, into the bottom of which the pipe P, which in the formcr apparatus enters tank D, passes, while it is connected to tank D by means of ,a pipe, V, having a valve, NV, opening toward` tank D, and capable of being adjusted to open at the pressure desired to be retained in the tank U. Three pipes, X, Y, and Z, pass from the bottoms of the tank E containing the neutral air, from the tank, D, which contains the liquor charged with the carbonio-acid gas, and from the tank U to a pump, A, the pipes X and Z, respectively, passing from the neutral-air tank and from the charged-liquor tank, discharging into the pumpfwhile the pipe Y receives the fluid from the pump andy passes it into the tank U.

The liquor is charged in the tank D in the same manner as in the former apparatus, and the vacuum-tank and neutral-air tank are operated likewise in the same manner; but in place of filling the liquor directly from the tank D into the siphon the pump A is used to pump the liquor into tank U, while the said pump at the same time is also used for pumping neutral air from the neutral-air tank into the tank U, which thus receives a charge of liquor charged with carbonio-acid gas and of neutral air, the liquor forced into the tank at a pressure above the pressure desired passing back into theliquor-tank through the pipe V and valve W.

The siphon 'is placed under the cock-tobe filled when a vacuum is created within it by connecting it with the vacuum-tank.v Neutral air is now admitted into the siphon at a suffcient pressure to produce the desired pressure in the siphon when the latter is lled, whereupon the liquor is at last admitted into the siphon from tank U, the pressure in which is sufficient to overcome the existing pressure in the siphon until the siphon has been filled to its desired capacity, when the pressure within the siphon and in the tank will equal each other, consequently stopping further filling. By thus filling the charged liquor into the siphon against a slightly smaller pressure the liquor will not foam, and consequently the siphons may be filled quicker and more satisfactorily than by the former apparatus,'the operation of which is somewhat simpler, as well as also its constructiomthan the last-described apparatus.
